Definitions

  • the present invention relates to a device for anchoring a coating on a molded wall such as, for example, a wall or a ceiling, a floor.
  • stripping is done by removing the boards and their supporting structures.
  • the insulation panels are then fixed to the slab via the anchoring means whose parts initially projecting are embedded in the molded slab.
  • the various solutions that have been proposed so far for making the anchoring devices can be classified in two categories, namely: the anchoring means which are incorporated in the insulation panels during their manufacture and the means of anchorages intended to be assembled on site at the time of their use.
  • the first solution makes it possible to offer a ready-to-use product at a more attractive price since it is manufactured in the factory using manufacturing means that ensure high production rates.
  • it avoids having to organize for these fasteners a distribution circuit, separate from that of the panels.
  • it suffers from a major disadvantage due to the fact that the panels equipped with projecting anchoring means become difficult to store and manipulate. This is why articulated anchoring devices have been proposed, which can be folded against the panels, during storage and transportation, and can take an extended position when using the panels. This is a more expensive and less effective solution because the stress due to articulation and tilting does not allow the use of forms best suited to obtain a good anchorage.
  • anchoring devices are used in the form of helical springs that are partially screwed into the insulation panels, the part emerging from the formwork being used to anchor, A solution of this type is described in the European patent application EP 0 034 545 .
  • the object of the invention is a solution that combines the advantages of the two previously mentioned solutions without understanding the disadvantages.
  • a device for anchoring a coating on a molded wall comprising a helical spring comprising a first part which is part of a substantially cylindrical shape and which is intended to be screwed into the insulation panel, and a second portion for anchoring in the wall at the time of molding.
  • this device is characterized in that the second part is in a substantially conical shape and extends the first part flaring.
  • the conical shape of the protruding portion of the panel has a very thin (that of the wire used for the realization of the spring).
  • the panels can be superimposed without loss of space.
  • the stiffness of the spring is a function of the diameter of the turns, the force to compress the conical portion of the spring will be relatively low. It is the same with regard to the punching action of the spring on the panel which compresses it during an overlay.
  • the risk of deterioration of this panel are minimal.
  • Another advantage of this solution is that in a stack of panels, the highest panel of the stack is slightly raised by the action of the springs, the other panels remaining properly stacked. This slight elevation of the panel allows the handlers to pass their fingers under the panel and get good grips. The handling of the panels is thus considerably facilitated.
  • the presence of the conical part of the spring facilitates the screwing of the device in the panels, whether it is a screwing on the site or a screwing factory: This conical part allows a better grip at the hand and better hold when using a screwdriver.
  • the turn of the conical portion may have a greater diameter than that of the turns of the cylindrical portion, so that one obtains at this junction l equivalent of a shoulder.
  • this shoulder will abut on the outer face of the panel by stopping the screwing. The operator will no longer have to worry about the depth of screwing.
  • the first turn of the second portion 3 has a substantially larger diameter than that of the first portion 2.
  • the junction between the two parts is achieved through a length of wire 4 which extends radially (at the image of a shoulder).
  • This spring 1 may advantageously be made of a galvanized or stainless steel wire or polymer.
  • the panels P 1 , P 2 are laid flat on a horizontal formwork table TC mounted on a support structure here constituted by straight legs PS (partially shown).
  • the springs 1 which constitute the fixing devices are screwed on the upper wall of the panels (here the panel P 1 ) so that only the second portion 3 (conical) is projecting with respect to said wall.
  • the operator places the metal reinforcements AM (reinforcement) and proceeds to pour the floor PL, for example with concrete, until the desired level be reached.
  • the operator can remove the formwork table TC and its support structure PS.
  • the anchoring devices 1 can be screwed down at the factory or even on the site just before the panels P 1 , P 2 are installed.
  • the panels P 1 , P 2 , P 3 equipped with anchoring devices, can be easily stacked for storage and transport ( figure 3 ).
  • Screwing anchoring devices described above can be done by hand or using a screwing device: Indeed, its shape lends itself perfectly to these two modes of screwing.
  • the figure 4 shows a screwing bell 6 which can be mounted in the mandrel of a conventional screwdriver.
  • This screwing bell 6 comprises a tubular body 7 open in its lower part and terminated in its upper part by a bottom 8 extended by a coaxial rod 9 adapted to engage in the mandrel of the screwdriver.
  • the lower face of the disc comprises a coaxial annular groove (groove) 11 of diameter substantially equal to that of said turn.
  • This cavity 11 comprises a protuberance intended to abut on the end of the spring so as to be able to drive it in rotation.
  • This core 13 is biased by a spring 14 so as to naturally assume an extended position in which it emerges outside the body 7 over a length substantially equal to that of the cylindrical portion 2 of the spring, a position in which it is retained. thanks to a limit stop (here a needle screw 15 which engages in an axial groove 16 of the core 13).
  • a limit stop here a needle screw 15 which engages in an axial groove 16 of the core 13.
  • the distance between the bottom of the annular cavity 11 and the lower end of the body 7 is substantially equal to the height of the conical portion 3 of the spring.
  • a radial notch 17 formed on the lower end of the body 7 allows the passage of the radial section 4 spring wire and its rotational drive.
  • the spring is guided (in particular by the core 13) and rotated by the screwing bell.
  • the lower end of the core 13 may have a conical shape.
